how to learn Unix/Linux command

[Robertlzw]

I want to learn the most commonly used Unix/Linux commands. For example, to use "grep" to list all lines that do not contain "ABC" in a file, or to list all file names starting with "a" under certain path.

I know that man pages are good sources for it. But they too comprehensive with all possible options. I am a kind of "go-by-example" person. So what is the best book/resource for me to learn these commands quickly? Thanks in advance.

This is a C++ forum though.

The best source for this is the man-pages, dude...
